Abstract
Abstract A method of manufacturing a water-release transfer is disclosed in which a design in a photopolymerizable ink is applied to a substrate having a water-soluble release coating and the design is subjected to photopolymerizing radiation, e.g. ultra-violet light, to cause the ink to polymerize to a solid state. Preferably the ink comprises a mixture of a liquid unsaturated monomer and a viscous or solid prepolymer, and one or both of the monomer and prepolymer contain acryloyl or methacryloyl groups. The invention includes water-release transfers manufactured using photopolymerizable inks.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
118 words
A water-release transfer which comprises a transferable design formed in a photopolymerized ink supported on a flexible water-permeable carrier substrate and having an intervening water-soluble release layer, which provides a surface capable of being wetted by said ink while in its unpolymerized state, between the substrate and the design, said design comprising a solid film of flexible and stretch-resisting, cross-linked polymer produced by photopolymerization of a liquid ink printed on the substrate and consisting essentially of a blend of rapidly photopolymerized, ethylenically unsaturated monomer and prepolymer containing pendant or terminal acryloyl or methacryloyl groups wherein the prepolymer has about 2 to 6 acryloyl or methacryloyl groups per molecule whereby on photopolymerization a cross-linked and flexible film is produced.
Claim 2
Dependent Claim
