Abstract
A product label in which a heat sensitive recording layer and a heat sensitive color forming layer for printing goods information are laminated on a substrate, the heat sensitive recording layer and the heat sensitive color forming layer form colors different from each other and the heat sensitive color forming layer forming an emphasis area. Partial disposition of the heat sensitive color forming layer for the emphasis area can provide a product label of inexpansive material cost and capable of heat sensitive recording for two or more colors with no color mixing under simple control.
Claims7
A product label comprising:
- a substrate;
- a heat sensitive recording layer laminated on the substrate for printing goods information;
- a desensitizing region partially provided on the heat sensitive recording layer which is decreased or inactivated for a color forming function so that the desensitizing region is in a state of scarcely forming a color even when applied with heat energy;
- and
- a heat sensitive color forming layer laminated on the desensitizing region of the substrate for forming a color different from that of the heat sensitive recording layer to form an emphasis area and printing goods information to be indicated in the emphasis area.
A label comprising:
- a substrate;
- a heat sensitive-recording layer provided on the substrate;
- a desensitizing region partially provided on the heat sensitive recording layer which is decreased or inactivated for a color forming function so that the desensitizing region is in a state of scarcely forming a color even when applied with heat energy;
- and
- a heat sensitive color forming layer provided on the desensitizing region of the substrate for forming a color different from that of the heat sensitive recording layer.
