Abstract
A photosensitive composition containing a compound having a group represented by formula(I) or (II), said group, when irradiated with actinic radiation, forming a carboxylic acid or a sulfonic acid: ##STR1## wherein R.sub.1 represents hydrogen, an alkyl group, or an aryl group; and R.sub.2 to R.sub.6 may be the same or different and each represents hydrogen, a halogen, an alkoxyl group, an aryloxyl group, cyano group, or an alkyl group, provided that at least one of R.sub.2 to R.sub.6 represents an alkoxyl or aryloxyl group and two of R.sub.2 to R.sub.6 may link to form a ring.
Claims16
A photosensitive composition containing a compound having a group represented by formula (II), said group, when irradiated with actinic radiation, forming a sulfonic acid:
- ##STR21## wherein R.sub.1 represents hydrogen, an alkyl group, or an aryl group;
- and
- R.sub.2 to R.sub.6 may be the same or different and each represents hydrogen, a halogen, an alkoxyl group, an aryloxyl group, cyano group, or an alkyl group, provided that at least one of R.sub.2 to R.sub.6 represents an alkoxyl or aryloxyl group and two of R.sub.2 to R.sub.6 may link to form a ring.
A photosensitive composition containing a compound having a group represented by formula (II), said group, when irradiated with actinic radiation, forming a sulfonic acid:
- ##STR24## wherein R.sub.1 represents hydrogen;
- and
- R.sub.2 to R.sub.6 may be the same or different and each represents hydrogen, a halogen, an alkoxyl group, an aryloxyl group, cyano group, or an alkyl group, provided that at least one of R.sub.2 and R.sub.3 represents an alkoxyl or aryloxyl group, and two of R.sub.2 to R.sub.6 may link to form a ring provided that R.sub.2 and R.sub.3 do not link to form a ring.
A photosensitive composition containing (a) a compound having a group represented by formula (I), said group, when irradiated with actinic radiation, forming a carboxylic acid:
- ##STR25## wherein R.sub.1 represents hydrogen;
- and
- R.sub.2 to R.sub.6 may be the same or different and each represents hydrogen, a halogen, an alkoxyl group, an aryloxyl group, cyano group, or an alkyl group, provided that at least one of R.sub.2 and R.sub.3 represents an alkoxyl or aryloxyl group, and two of R.sub.2 to R.sub.6 may link to form a ring provided that R.sub.2 and R.sub.3 do not link to form a ring, and (b) a resin which is insoluble in water but soluble in an aqueous solution of an alkali,
- wherein the compound having the group represented by formula (I) is a compound containing at least 1 mol % of a structural unit derived from a monomer represented by the following formula (III) or (V):
- ##STR26## wherein R represents hydrogen, a halogen, or an alkyl group;
- R.sub.1 to R.sub.6 in formula (III) and (V) have the same meaning as in formula (I), and two of R.sub.2 to R.sub.6 may link to form a ring provided that R.sub.2 and R.sub.3 do not link to form a ring;
- and
- A represents a single bond or a divalent, aliphatic or aromatic hydrocarbon group.
