Abstract:
A radiation sensitive mixture useful for producing relief patterns contains(a) a polymeric binder which is insoluble in water but soluble in aqueous alkaline solutions and(b) an organic compound whose solubility in an aqueous alkaline developer is increased by the action of acid and which contains at least one acid cleavable group and also a group which on irradiation forms a strong acid,wherein the polymeric binder (a) contains from 5 to 40 mol % of monomer units having ##STR1## in copolymerized or cocondensed form or the ##STR2## introduced by polymer analogous reaction with the proviso that the radical R contains from 5 to 9 carbon atoms.
Abstract:
The radiation-sensitive mixture contains(a) a polymeric binder which is insoluble in water but soluble in aqueous alkaline solutions and(b) an organic compound whose solubility in an aqueous alkaline developer is increased by the action of an acid and which contains one or more acid-cleavable groups,the polymeric binder (a) being a copolymer which contains o-nitrobenzyl groups.The novel radiation-sensitive mixture is particularly suitable for the production of photoresists.
Abstract:
Copolymers useful in particular for producing two-layer resists and fabricating semiconductor devices contain from 5 to 50 mol % of monomers having o-nitrocarbinol ester groups, from 95 to 50 mol % of an olefinically unsaturated silicon-containing organic compound, from 0 to 20 mol % of an olefinically unsaturated carboxylic acid and from 0 to 25 mol % of other copolymerizable monomers.
Abstract:
A process is disclosed for producing moldings, in which a pigmented coating composition (P) and a free-radically crosslinkable coating composition (K), which after crosslinking to completion produces a transparent coating (KE) are applied to a support sheet, wherein a dried but as yet not completely crosslinked coating (KT) is produced from the coating composition (K), the coated support sheet is shaped and is injection backmolded or foam-backed, and the coating (KT) is cured or aftercured; the crosslinkable coating composition (K) comprising a free-radically crosslinkable component (KK) which contains hydrogen bond forming structural elements.
Abstract:
The present invention relates to aqueous skin or hair cosmetic preparations which comprise at least one polymer A which comprises, in copolymerized form, at least one ester of (meth)acrylic acid, at least one olefinically unsaturated, free-radically polymerizable anionogenic or anionic compound, at least one free-radically polymerizable olefinically unsaturated urethane-group-containing compound which comprises no silicone groups and, if appropriate, further free-radically polymerizable compounds.
Abstract:
The use of high-functionality highly branched polyetheramine polyols to coat substrates such as metal surfaces or components made of plastic permits improved adhesion of further coatings.
