The substrate has a front side and a back side opposite the front side. The thermally-sensitive coating is disposed on the front side of the substrate. The adhesive is disposed on a portion of the back side of the substrate. The adhesive may comprise emulsion polymer particles and high-aspect reinforcement particles dispersed within the emulsion polymer particles to provide a relatively high level of reinforcement per reinforcement particle. The adhesive may include a tapered surface interconnecting first and second adhesive edge surfaces which extend substantially parallel to a longitudinally-extending axis. The substrate may comprise a transparent material. The thermally-sensitive coating may comprise a clear material. ## Claims ### Claim 1 Linerless label media comprising: a substrate having a front side and a back side opposite the front side; a thermally-sensitive coating disposed on the front side of the substrate; and adhesive disposed on a portion of the back side of the substrate, wherein the adhesive comprises emulsion polymer particles and high-aspect reinforcement particles dispersed within the emulsion polymer particles to provide a relatively high level of reinforcement per reinforcement particle. ### Claim 2 (depends on 1) Linerless label media according to claim 1, wherein the high-aspect reinforcement particles comprise at least one of needles, fibers, platelets, and sheets. ### Claim 3 (depends on 2) Linerless label media according to claim 2, wherein the high-aspect reinforcement particles are trapped in spaces between the emulsion polymer particles. ### Claim 4 (depends on 3) Linerless label media according to claim 3, wherein (i) the substrate has a longitudinally-extending axis, and (ii) the adhesive includes a tapered surface interconnecting first and second adhesive edge surfaces which extend substantially parallel to the longitudinally-extending axis. ### Claim 5 (depends on 3) Linerless label media according to claim 3, wherein (i) the substrate comprises a transparent material, and (ii) the thermally-sensitive coating comprises a clear material. ### Claim 6 (depends on 1) Linerless label media according to claim 1, further comprising: a core; and a web having a longitudinally-extending axis and wound on the core along the axis, the web including the substrate, the thermally-sensitive coating, the adhesive, and a release coating disposed on the front side of the substrate to prevent the adhesive from sticking to the front side of the substrate when the web is wound around the core. ### Claim 7 (depends on 6) Linerless label media according to claim 6, further comprising at least one longitudinal perforation extending along a direction parallel to the axis and dividing the web into a first web portion on which the adhesive and the release coating are disposed and a second web portion which is substantially devoid of adhesive. ### Claim 8 Linerless label media comprising: a substrate having (i) a longitudinally-extending axis, (ii) a front side, and (iii) a back side opposite the front side; a thermally-sensitive coating disposed on the front side of the substrate; and adhesive disposed on a portion of the back side of the substrate, wherein the adhesive includes a tapered surface interconnecting first and second adhesive edge surfaces which extend substantially parallel to the longitudinally-extending axis. ### Claim 9 (depends on 8) Linerless label media according to claim 8, wherein the tapered surface tapers downwards from the first adhesive edge surface towards the second adhesive edge surface. ### Claim 10 (depends on 9) Linerless label media according to claim 9, wherein the first adhesive edge surface is located closer to the longitudinally-extending axis than the second adhesive edge surface. ### Claim 11 (depends on 8) Linerless label media according to claim 8, wherein the adhesive comprises emulsion polymer particles and high-aspect reinforcement particles dispersed within the emulsion polymer particles to provide a relatively high level of reinforcement per reinforcement particle. ### Claim 12 (depends on 8) Linerless label media according to claim 8, wherein (i) the substrate comprises a transparent material, and (ii) the thermally-sensitive coating comprises a clear material. ### Claim 13 (depends on 8) Linerless label media according to claim 8, further comprising: a core; and a web wound on the core along the longitudinally-extending axis, the web including the substrate, the thermally-sensitive coating, the adhesive, and a release coating disposed on the front side of the substrate to prevent the adhesive from sticking to the front side of the substrate when the web is wound around the core. ### Claim 14 (depends on 13) Linerless label media according to claim 13, further comprising at least one longitudinal perforation extending along a direction parallel to the axis and dividing the web into a first web portion on which the adhesive and the release coating are disposed and a second web portion which is substantially devoid of adhesive. ### Claim 15 Linerless label media comprising: a substrate having a front side and a back side opposite the front side, wherein the substrate comprises a transparent material; a thermally-sensitive coating disposed on the front side of the substrate, wherein the thermally-sensitive coating comprises a clear material; and adhesive disposed on a portion of the back side of the substrate. ### Claim 16 (depends on 15) Linerless label media according to claim 15, wherein clear material of the thermally-sensitive coating comprises a clear color for a transparent see through effect. ### Claim 17 (depends on 15) Linerless label media according to claim 15, wherein the adhesive comprises emulsion polymer particles and high-aspect reinforcement particles dispersed within the emulsion polymer particles to provide a relatively high level of reinforcement per reinforcement particle. ### Claim 18 (depends on 15) Linerless label media according to claim 15, wherein (i) the substrate has a longitudinally-extending axis, and (ii) the adhesive includes a tapered surface interconnecting first and second adhesive edge surfaces which extend substantially parallel to the longitudinally-extending axis. ### Claim 19 (depends on 15) Linerless label media according to claim 15, further comprising: a core; and a web wound on the core along the longitudinally-extending axis, the web including the substrate, the thermally-sensitive coating, the adhesive, and a release coating disposed on the front side of the substrate to prevent the adhesive from sticking to the front side of the substrate when the web is wound around the core. ### Claim 20 (depends on 19) Linerless label media according to claim 19, further comprising at least one longitudinal perforation extending along a direction parallel to the axis and dividing the web into a first web portion on which the adhesive and the release coating are disposed and a second web portion which is substantially devoid of adhesive.
