Abstract
Microcapsules are disclosed containing (a) a vinyl compound which has at least two polymerizable, ethylenically unsaturated groups linked to each other through a linking group comprising a chemical bond capable of being split by the action of an acid, (b) a thermal polymerization initiator, and (c) one or more compounds capable of producing acid when irradiated with actinic radiation. A light-sensitive recording material is also disclosed, which has on its support the above-described microcapsules or a thermally cured product thereof.

Microcapsules containing (a) a vinyl compound which has at least two polymerizable, ethylenically unsaturated groups linked to each other through a linking group comprising a chemical bond capable of being split by the action of an acid, (b) a thermal polymerization initiator, and (c) one or more compounds capable of producing acid when irradiated with actinic radiation.
A light-sensitive recording material which has on its support microcapsules containing (a) a vinyl compound represented by formula (I) or (II) ##STR13## wherein R.sub.1 represents a hydrogen atom, a halogen atom, or an unsubstituted or substituted alkyl group;
- R.sub.2 and R.sub.3 each represents a hydrogen atom, a substituted or unsubstituted alkyl, alkenyl, aryl, or aralkyl group, or --OR.sub.5 ;
- R.sub.4 represents an unsubstituted or substituted n-valent aliphatic or aromatic hydrocarbon;
- R.sub.5 represents an unsubstituted or substituted alkyl, aryl, or aralkyl group;
- A represents a single chemical bond, ##STR14## R.sub.6 represents an unsubstituted or substituted divalent aliphatic or aromatic hydrocarbon;
- R.sub.7 represents a hydrogen atom, an unsubstituted or substituted alkyl, aryl, or aralkyl group, or --CO--R.sub.8 ;
- R.sub.8 represents an unsubstituted or substitited alkyl, aryl, or aralkyl group;
- m represents an integer of from 2 to 4;
- and n represents an integer of 2 or more, (b) a thermal polymerization initiator, and (c) one or more compounds capable of producing acid when irradiated by actinic radiation, or a thermally cured product of said microcapsules.
