Abstract: A mixture having (A) a polymer obtain by polymerizing at least one free-radically polymerizable compound; and (B) at least one compound having at least one ethylenically unsaturated, free-radically polymerizable group and having a weight-average molecular weight Mw of less than 5000 g/mol, wherein at least 10% by weight of compounds (B) are one or more compounds B1 with at least one nonaromatic ring system.

Abstract: A description is given of a process for preparing solutions of radiation-sensitive, free-radically polymerizable organic compounds, where a first starting compound, which has an acid halide group, and a second starting compound, which has an alcoholic hydroxyl group, are esterified with one another in a solvent or in a solvent mixture. The solvent comprises one or more ketones having a boiling point of below 150° C. under atmospheric pressure (1 bar), or the solvent mixture is composed to an extent of at least 50% by weight of said ketones. One of the two starting compounds has at least one radiation-sensitive group and the other of the two starting compounds has at least one ethylenically unsaturated, free-radically polymerizable group.
