| titleOfInvention | RADIATION-SENSITIVE MIXTURE AND PRODUCTION OF RADIATION-SENSITIVE RECORDING MATERIAL |
| abstract | Positive-working radiation-sensitive mixt. consists of a polymeric binder, which is insol. in water but soluble in aq. alkaline solns., and a 1,2-quinone-diazide and/or a combination of a cpd. forming a strong acid where exposed to actinic radiation and a cpd. with hydrolysable C-O-C linkage(s). The binder is a polyer with (poly)hydroxyaralkyl (substd.) acrylate units of formula (I): Y = a (poly)hydroxyaralkyl gp. of formula (II): R1 = H, halogen, CN or alkyl; R2 and R3 independently = H, alkyl or aryl; R4, R5 and R6 independently = H, halogen, alkyl, alkoxy or aryl; X = the atoms needed to complete a mono- or polynuclear carbocyclic aromatic ring system; n = 1, 2 or 3. Pref. Y = 4-hydroxybenzyl, opt. with 1-4C alkyl or halogen substit(s). in the 3- and/or 5-positions; or 2-hydroxybenzyl methacrylate, opt. with a 1-4C alkyl or halogen substit. in the 3-position and/or a 1-4C alkyl, halogen or opt. alkyl-, alkoxy- or halogen-substd. aryl substit. in the 5-position. The binder also contains unit(s) of formula (III): -(-C(R7)(R8)-C(R9)(R10)-)- (III); R7 = H; R8 = H or COOH and R9 = alkyl, alkoxy, alkoxycarbonyl, acyl, acyloxy, aryl, aryloxycarbonyl, HCO, CN, COOH, OH or aminocarbonyl; esp. 1-4C alkyl, 1-8C alkoxy, 2-13C alkoxycarbonyl, 2-18C acyloxy, 6-10C aryl or 7-11C aryloxycarbonyl, in which the aryl gps. may have OH substits.; or R8 + R9 = a carboxylic anhydride gp. or opt. alkyl-substd. imide; R10 = H, halogen or alkyl. |
