  • Shoot and run printing materials
    Patent number: 5395734
    Abstract: Acid-sensitive polymers and imageable articles employing them are disclosed. In particular, photosensitive compositions are disclosed 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 A has the formula --T--(C.dbd.O)OCR.sup.1 R.sup.2 OR.sup.3, and B has the formula --T--(C.dbd.O)OR.sup.4 Si(R.sup.5).sub.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 group having from 3 to 36 carbon atoms; R.sup.5 represents an alkyl group, aryl group, an alkoxy group, an aryloxy group, an acyloxy group, or a trialkylsiloxy group; and R.sup.4 and T represents a divalent linking group wherein T is bonded to the polymer backbone and R.sup.

  • Alkoxyalkyl ester solubility inhibitors for phenolic resins
    Patent number: 5085972
    Abstract: Solubility inhibitors for phenolic resins are disclosed, which when used in phenolic resin/iodonium salt positive printing plate constructions result in significantly increased sensitivity. The solubility inhibitors contain an alkoxyalkyl ester moiety. Also disclosed are presensitized lithogaphic plates containing the solubility inhibitors and a process for developing a photoimage.
