Abstract
A method of decorating laminated glass is disclosed. A pigment package composition comprising a cross-linkable thermoset resin, a crosslinker capable of crosslinking the thermoset resin, and a pigment is applied to a glass substrate. The crosslinker and thermoset resin are cured at a relatively low temperature (ca. 400° F.). The use of an organic based pigment composition allows use of thinner glass sheets than with traditional ceramic enamel pigment compositions.
Claims17
A method of forming a laminated decorated glass structure comprising:
- a. applying to a first glass substrate an organic pigment package comprising, prior to curing,
- i. a crosslinkable thermoset resin selected from the group consisting of polyesters, urethanes, vinyl polymers, acrylics, styrenes, polyolefins, polycarbonates, copolymers thereof, and blends thereof,
- ii. a crosslinker capable of crosslinking the thermoset resin, selected from the group consisting of:
- amines, amino resins, amido resins, isocyanates, ureas, and dialdehydes, and
- iii. a pigment,
- wherein prior to curing, the crosslinker and thermoset resin are present in an equivalence ratio of about 0.2 to about 1.2;
- b. curing the crosslinker and the thermoset resin to form a cured layer on the first substrate;
- c. stacking an acetal layer and a second glass substrate onto the cured layer such that the acetal and the cured layer lie between the first substrate and a second glass substrate;
- and
- d. heating the first and second stacked glass substrates to flow the acetal layer and effect interpenetration of the acetal layer with the cured layer.
