A process for the formation of an imaged article comprising the steps of exposing an imageable article comprising a substrate coated with a photosensitive composition comprising (a) a photoinitiator which generates an acid upon exposure to radiation;

• and (b) a polymer having acid labile groups pendant from the polymer backbone, said acid labile pendant groups comprising at least one each of A and B, wherein B has the formula --T--(C.dbd.O)OR.sup.4 Si(R.sup.5).sub.3 , and A has the formula --T--(C.dbd.)OCR.sup.1 R.sup.2 OR.sup.3, wherein R.sup.1 and R.sup.2 each represent H or an alkyl group with the proviso that at least one of R.sup.1 and R.sup.2 must be hydrogen;
• R.sup.3 represents an alkyl group;
• or any two of R.sup.1, R.sup.2, and R.sup.3 may together form a ring having from 3 to thirty-six carbon atoms;
• R.sup.5 represents an alkyl group, an aryl group, an alkoxy group, an aryloxy group, an acyloxy group, or a trialkylsiloxy group;
• and R.sup.4 and T independently represent a carbon-to-carbon bond or a divalent linking group wherein T is bonded to the polymer backbone and R.sup.4 is not bonded to the polymer backbone, to a range of radiation absorbed by the photoinitiator thereby forming a latent image bearing article;
• contacting the first latent image bearing article with a hydrophilizing agent to form a second latent image bearing article;
• and then contacting the second latent image bearing article with a dye solution to form an imaged article.

A process for forming and fixing an imaged article comprising the steps of:

• a) exposing an imageable article comprising a substrate coated with a photosensitive composition comprising (a) a photoinitiator which generates an acid upon exposure to radiation;
• and (b) a polymer having acid labile groups pendant from the polymer backbone, said acid labile pendant groups comprising at least one each of A and B, wherein B has the formula --T--(C.dbd.O)OR.sup.4 Si(R.sup.5).sub.3,and A has the formula --T--(C.dbd.O)OCR.sup.1 R.sup.2 OR.sup.3, wherein R.sup.1 and R.sup.2 each represent H or an alkyl group with the proviso that at least one of R.sup.1 and R.sup.2 must be hydrogen R.sup.3 represents an alkyl group;
• or any two of R.sup.1, R.sup.2, and R.sup.3 may together form a ring having from 3 to thirty-six carbon atoms;
• R.sup.5 represents an alkyl group, an aryl group, an alkoxy group, an aryloxy group, an acyloxy group, or a trialkylsiloxy group;
• and R.sup.4 and T independently represent a carbon-to-carbon bond or a divalent linking group wherein T is bonded to the polymer backbone and R.sup.4 is not bonded to the polymer backbone, to radiation within a range absorbed by said photoinitiator to form a first latent image bearing article;
• b) heating said first latent image bearing article to a temperature greater than about 100.degree. C. to form a second latent image bearing article, and
• c) cooling said heated latent image bearing article to below 40.degree. C. to form a third latent image bearing article, and
• d) exposing said modified latent image bearing article to white light to form a fourth latent image bearing article, and
• e) contacting said fourth latent image bearing article with hydrophilizing agent to form a fifth latent image bearing article, and
• f) applying ink to said fifth latent image bearing article to form an imaged article.
