SHEET MATERIAL RENDERED LESS FLEXIBLE BY COATING WITH A MATERIAL CURABLE WITH ACTINIC LIGHT

摘要

A flexible sheet material provided with a gelled flexible coating of an organic material comprising a thermoplastic polymer containing, as a plasticizer, one or more ethylenically unsaturated monomeric materials and a photosensitive catalyst for initiating polymerization of the monomeric materials. The organic material is curable on exposure to actinic light to produce a less flexible, and more preferably, an inflexible coating on the sheet. The material can be used as a wall covering.
