Abstract
Abstract The material comprises a support coated on one side with microcapsules in which are encapsulated a vinyl compound, a photopolymerization initiator, and a first color forming component being capable of undergoing a color reaction with a second color forming component to cause color formation. The second color forming component is provided on the same side of the support outside the microcapsules.

Claim 1
Independent Claim
57 words
A light and heat-sensitive recording material, comprising: a support base; having on one surface thereof a plurality of microcapsules containing a vinyl compound, a photopolymerization initiator, and a first color forming component capable of undergoing a color reaction with a second color forming component to form a color; and, outside said microcapsules said second color forming component.
Claim 2
Dependent Claim
57 words
A light and heat-sensitive recording material, comprising: a support base; having on one surface thereof a plurality of microcapsules containing a vinyl compound, a photopolymerization initiator, and a first color forming component capable of undergoing a color reaction with a second color forming component to form a color; and, outside said microcapsules said second color forming component.
Claim 3
Dependent Claim
41 words
