Abstract
Abstract A unitary laminate is produced bearing a permanently visible pattern of indicia. The laminate comprises a binder layer, containing pigment, and a transparent layer, each formed of hydrophobic synthetic polymer. Sublimable dyestuff is heat transferred from an auxiliary carrier web to the transparent layer to submerge the pattern into an external surface of the transparent layer.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
114 words
In a sublimination transfer dyeing process in which sublimable dyestuff is transferred from an auxiliary carrier web to a support stratum, the improvement whereby a print can be formed on a non-textile stratum, comprising the steps of: (a) laminating together as said support stratum (i) a binder layer comprising polyester resin containing 50-85 weight percent glass fiber and containing pigment and (ii) on said binder layer, a substantially pigment-free transparent layer of thermosettable material receptive to sublimatic dyestuff selected from alkyd resin, melamine formaldehyde resin and combinations thereof; (b) curing to form a thermoset, heat resistant laminate; and (c) transferring said dyestuff to said transparent layer by heat-induced sublimation from said auxiliary carrier web.
Claim 2
Dependent Claim

Claim 6
Dependent Claim
105 words
In a sublimation transfer dyeing process in which sublimable dyestuff is transferred from an auxiliary carrier web to a support stratum, the improvement whereby a print can be formed on a metal substrate, comprising the steps of: (a) laminating together as said support stratum (i) a binder layer applied directly to a rigid metal substrate, said binder layer containing pigment and (ii) directly on said binder layer, a substantially pigment-free transparent layer of thermosettable material receptive to sublimatic dyestuff; (b) curing to form a thermoset, heat resistant laminate; and (c) transferring said dyestuff to said transparent layer by heat-induced sublimation from said auxiliary carrier web.
