| abstract |
The present invention relates to a novel positive photosensitive composition having: at least one photoacid generator; at least one varnish-type phenolic resin polymer; at least one polymer having a polymer backbone, the polymer comprising the following structure : wherein R1 to R5 are independently -H or -CH3, A is a linear or branched C1-C10 alkyl group, B is a C1-C12 alkyl group or an alicyclic group, and D is a chemical bond or a carboxylate. a group (wherein the carbonyl carbon is bonded to the polymer backbone) or a -COOCH2- group (wherein the carbonyl carbon is bonded to the polymer backbone), the Ar is substituted or unsubstituted An aromatic group or a heteroaromatic group, E is a linear or branched C2-C10 alkylene group, and a G-based acid cleavable group. The invention further relates to a method of using the novel composition to form an image. |
