Patent ID: 8333865

Claim:
A method for mounting printing plates to printing cylinders or sleeves, which comprises mounting said printing plates to said cylinders or sleeves with a pressure-sensitive adhesive tape having a flat carrier material which is coated on both sides with a pressure-sensitive adhesive, the side of the flat carrier material upon which said printing plate is mounted being coated with a weakly adhering pressure-sensitive adhesive having a bond strength of <2.5 N/cm and comprising polymers formed from a monomer mixture of at least the following components: i.a) 49.5%-89.5% by weight (based on the monomer mixture) of acrylic esters and/or methacrylic esters and/or of free acids corresponding to said acrylic esters and/or methacrylic esters, with the following formula: CH 2 ═C(R 1 )(COOR 2 ), where R 1 ═H or CH 3 and R 2 is an alkyl radical having 1 to 10 carbon atoms or H and a homopolymer thereof possesses a static glass transition temperature of <−30° C.; i.b) 10% to 40% by weight (based on the monomer mixture) of acrylic esters and/or methacrylic esters with the following formula: CH 2 ═C(R 3 )(COOR 4 ), where R 3 ═H or CH 3 and R 4 is a cyclic alkyl radical having at least 8 carbon atoms or a linear alkyl radical having at least 12 carbon atoms and a homopolymer thereof possesses a static glass transition temperature of at least 30° C.; i.c) 0.5%-10% by weight (based on the monomer mixture) of acrylic esters and/or methacrylic esters with the following formula: CH 2 ═C(R 3 )(COOR 5 ), where R 3 ═H or CH 3 and R 5 ═H or an aliphatic radical containing a functional group X, X comprising COOH, OH, —NH, NH 2 , SH, SO 3 H, and a homopolymer thereof possesses a static glass transition temperature of at least 30° C., said polymers being crosslinked with a metal chelate crosslinker, and the side of the flat carrier material that is mounted to said cylinders or sleeves being coated with a more strongly adhering pressure-sensitive adhesive.
