Claim 6:
7. The cylinder sleeve of claim 6, wherein the one or more compounds having two or more ethylenically unsaturated groups are selected from the group consisting of:
I. one or more compounds according to formula (I):

R3—OC(O)—NH—R1—[NH—C(O)—O—R2—O—C(O)—NH—R5]n—NH—C(O)O—R4  (I)

wherein R3 and R4, independently of each other, are ethylenically unsaturated groups, wherein n is an integer in the range of from 1 to 1000,
wherein R1, R2, and R5, independently of each other, are divalent linking groups;

II. one or more compounds according to formula (II):

JYm  (II)

wherein J is an m-valent organic group, wherein m is an integer in the range of from 2 to 100, preferably in the range of from 2 to 4, wherein each Y, independently of each other, is a group according to formula (II.1):

R3—OC(O)—NH—R1—[NH—C(O)—O—R2—O—C(O)—NH—R5]n-NH—C(O)O—  (II.1)

or according to formula (II.2):

—OC(O)—NH—R1—[NH—C(O)—O—R2—O—C(O)—NH—R5]n-NH—C(O)O—R4  (II.2)

wherein R3 and R4, independently of each other, are ethylenically unsaturated groups, wherein n is an integer in the range of from 1 to 1000,
wherein R1, R2, and R5, independently of each other, are divalent linking groups;

III. a compound having a polyurethane backbone, obtainable and/or obtained by reacting a tri- or higher-functional isocyanate with a diol or a tri- or higher-functional polyol;
IV. a compound having a polyurethane backbone, obtainable and/or obtained by reacting a tri- or higher-functional polyol with a diisocyanate or a tri- or higher functional isocyanate; and
V. a compound, obtainable and/or obtained by reacting a diol with a diisocyanate, wherein the two or more ethylenically unsaturated groups R3 and R4, independently of each other, are preferably groups according to formula (III):

CH2═C(X)—C(O)O-L-  (III)

wherein X is hydrogen or a methyl group, and
wherein L is a divalent group.
