Abstract (en)
A foam plastics sheet material, such as a wallcovering, comprises a substrate web (10, 20) a printed pattern, or overall coating, (11, 21) and a foamable coating (12a, 12b, 22). The print composition includes an organic pigment and the foamable coating is selected to provide a migration path for the pigment. The degree of migration is dependent upon the foam thickness and hence graduated colour tones (30, 31, 32) can be derived from a single printing by control of foam thickness. In a preferred process, the foam thickness control is obtained by pre-embossing the substrate web. The print pattern or overall coating can include a foaming agent.
