Patent ID: 7435526

Claim:
A positive photosensitive composition comprising: (A) a compound capable of generating a sulfonic acid represented by formula (X) below upon irradiation with one of an actinic ray and radiation; and (B) a resin capable of decomposing under the action of an acid to increase the solubility in an alkali developer: wherein the R 1a to R 13a groups each represents a hydrogen atom, an alkyl group, a haloalkyl group, a halogen atom or a hydroxyl group; A 1 and A 2 , which are the same or different, each represents a hetero atom-containing divalent linkage group; m 1 to m 5 , which are the same or different, each represents an integer of 0 to 12; and p represents an integer of 0 to 4; and wherein the number of fluorine atoms in the sulfonic acid represented by formula (X) is smaller than the number of hydrogen atoms in the sulfonic acid represented by formula (X).
