ABSTRACT:
Method of dye absorption into the surface of plastics is accomplished by placing polyolefin film between a dye transfer paper and a sheet of thermoplastic and applying pressure and heat thereto. The heat applied is sufficient to sublime the dyes though the film to the plastic sheet. The dyes are absorbed into the surface of the plastic with the design intact. The materials are then cooled and separated and a decorated plastic sheet or article with wear-proof design is obtained. Thermoset plastics are similarly dye penetrated in this manner during the curing thereof.
In mold dye decoration and penetration of thermoplastics and thermoset plastics is also disclosed.
Further, post-pressure dye transfer to plastic sheet and plastic articles is disclosed.
