Abstract
1281905 Light- and heat-sensitive print-out materials forming dye images on exposure EASTMAN KODAK CO 6 Oct 1969 [30 Oct 1968] 49024/69 Heading G2C A radiation-sensitive material comprises a support carrying a layer of a composition comprising a mixture of (A) a pyridinium or pyrimidinium salt and (B) a heterocyclic ketomethylene compound in which a keto group and a methylene group each form part of the ring or a reactive cyclic ammonium quaternary salt compound having adjacent the quaternary N atom in the heterocyclic ring a reactive methine group which may be substituted with an alkyl group, (A) and (B) being such that when subjected to light and/or heat they react to form a dye. The component (A) may have the formula: - wherein R 1 is H, unsubstituted or substituted alkyl or an aryl group; R 2 is H, halogen, unsubstituted or substituted alkyl or an aryl or amino group; R 3 is H, unsubstituted or substituted alkyl or an aryl group; and X<SP>-</SP> is a salt-forming anion, e.g. pyrimidinium or pyridinium acetate or 2-amino- 1-methyl-pyrimidinium-p-toluenesulphonate. The heterocyclic ketomethylene compound may have the formula:- wherein Z is O or S; and R 4 and R 4a are each unsubstituted or substituted alkyl or an aryl group, or wherein R 5 is H, unsubstituted or substituted alkyl or an aryl group; and R 6 is unsubstituted or substituted alkyl or an aryl group, or wherein R 7 is unsubstituted or substituted alkyl or an aryl group. The reactive cyclic ammonium quaternary salt may have the formula: - wherein R 8 and R 9 are each alkyl and X<SP>-</SP> is a saltforming anion. The radiation-sensitive material may be made by imbibing the components (A) and (B) into an absorbent support or into an absorbent layer coated on a support.
