Thermal recording material

A heat-sensitive recording material, comprising a heat-sensitive recording layer containing at least one acid hydrazide compound represented by the following general formula (I): ##STR1## wherein X.sub.1 and X.sub.2 each independently represent a hydrogen atom, a hydroxyl group, a halogen atom or an alkyl group or alkoxy group having 1 to 10 carbon atoms, A represents --CO-- or --SO.sub.2 --, n is 1 or 2, when n is 1, R.sub.1 represents an alkyl group, an aryl group, a hydroxyaryl group, an alkoxyaryl group, or an alkylaryl group having 1 to 22 carbon atoms and when n is 2, R.sub.1 represents an alkylene group or arylene group having 1 to 18 carbon atoms or a direct bond.

Heat-sensitive recording material

The heat-sensitive recording material of the present invention comprises a heat-sensitive recording layer containing at least one resorcylic anilide derivative represented by the following general formula: ##STR1## wherein R.sub.1 represents an alkyl or alkoxy, group having 1 to 4 carbon atoms and R.sub.2 represents a hydrogen atom or an alkyl or alkoxy group having 1 to 4 carbon atoms.

Photopolymerizable composition and photopolymerizable element

Improved clarity and resistance to deterioration on heating of polyvinyl fluoride and vinyl chloride polymers is obtained by employing a stabilizer composition consisting essentially of (A) a heterocyclic nitrogen compound having as part of a 5 or 6 membered heterocyclic ring the group ##STR1## in which R is hydrogen, aryl, or alkyl having 1 to 12 carbon atoms, and X is oxygen or sulfur, and (B) one or more 1,2-epoxides, organic phosphites, or stannous tin, zinc, magnesium, aluminum, potassium, sodium, calcium, strontium, or barium salts of non-nitrogenous monocarboxylic acids having from 6 to 24 carbon atoms or hydrocarbon-substituted phenols having from about 10 to about 30 carbon atoms.
