Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 125 words
Radiation-sensitive crystalline polyacetylenic amine salts having the structural formula: D - (CH.sub.2).sub.x (C.tbd.C).sub.n (CH.sub.2).sub.y -COO.sup.- A.sup.+ wherein: n is an integer greater than 1; x and y are each an integer from 0 to 10; A is NRR 1 R 2 R 3 wherein R, R 1 , R 2 and R 3 are H, alkyl of from 1 to 15 carbon atoms, aryl or substituted alkyl having substituents chosen from the group consisting of hydroxy, amino, carboxy and methoxy substituents; D is selected from the group consisting of Ch 3 , coor 4 , and Conhr 5 , wherein R 4 is H or lower alkyl, R 5 is substituted alkyl of from 3 to 8 carbon atoms in which the substituent is alkylthio.
Claim 2
Dependent Claim 125 words
Radiation-sensitive crystalline polyacetylenic amine salts having the structural formula: D - (CH.sub.2).sub.x (C.tbd.C).sub.n (CH.sub.2).sub.y -COO.sup.- A.sup.+ wherein: n is an integer greater than 1; x and y are each an integer from 0 to 10; A is NRR 1 R 2 R 3 wherein R, R 1 , R 2 and R 3 are H, alkyl of from 1 to 15 carbon atoms, aryl or substituted alkyl having substituents chosen from the group consisting of hydroxy, amino, carboxy and methoxy substituents; D is selected from the group consisting of Ch 3 , coor 4 , and Conhr 5 , wherein R 4 is H or lower alkyl, R 5 is substituted alkyl of from 3 to 8 carbon atoms in which the substituent is alkylthio.
