Abstract
Abstract Photosensitive compositions which contain as a photosensitive resin prepared by the condensation of the co-condensated novolak resin of the mixture of phenols such as in a combination of tert-butyl (or tert-octyl) phenol and phenol and/or cresol and formaldehyde, with o-quinonediazido sulfonic (or carboxylic) acid or contain said novolak resin as an additive for a photosensitive o-quinonediazido compound are discosed.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
127 words
A photosensitive composition which comprises a photosensitive resin as an active component which is prepared by condensating an alkali-soluble co-condensated novolak resin prepared by the condensation of a mixture of a mole ratio of 1:9-9:1 of at least one compound represented by the formula (I): ##STR4## wherein R is an alkyl group having 3 to 12 carbon atoms or phenyl group, at least one of phenol and a methyl-substituted derivative thereof, and formaldehyde in 50-100 mole % relative to said phenol mixture, with a o-quinonediazido compound represented the formula (II) or (III): ##STR5## wherein X is --SO 2 Y or --COY group in which Y is a removable group, in an amount of 20 to 100 mole % based on the hydroxy groups in the novolak resin.
Claim 2
Dependent Claim
127 words
A photosensitive composition which comprises a photosensitive resin as an active component which is prepared by condensating an alkali-soluble co-condensated novolak resin prepared by the condensation of a mixture of a mole ratio of 1:9-9:1 of at least one compound represented by the formula (I): ##STR4## wherein R is an alkyl group having 3 to 12 carbon atoms or phenyl group, at least one of phenol and a methyl-substituted derivative thereof, and formaldehyde in 50-100 mole % relative to said phenol mixture, with a o-quinonediazido compound represented the formula (II) or (III): ##STR5## wherein X is --SO 2 Y or --COY group in which Y is a removable group, in an amount of 20 to 100 mole % based on the hydroxy groups in the novolak resin.
Claim 3
Dependent Claim
34 words
