摘要

PURPOSE: An aqueous protective coating agent is provided which is suitable for protecting the lacquer surface of a new automobile and can be easily peeled off as a foil-like film after using the agent. CONSTITUTION: A aqueous coating agent contains as binding agents in the form of aqueous polymer dispersions the following: A) 50 to 90 wt% of one or more thermoplastic copolymers of at least one C2-C4 olefin and of at least one vinyl ester of a C2-C11 monocarboxylic acid, wherein olefin(s) and vinyl ester are present in a weight ratio from 10:90 to 40:60 and together account for at least 80 wt% of the copolymer; B)10 to 50 wt% of one or more thermoplastic (meth)acryl copolymer, which are ree from comonomers with nitrile and amide groups and which consist of at east 50 wt% (meth)acrylic acid esters from C1-C18 alcohols, and C) 0 to 30 wt% of one or more copolymers different from A) and B), wherein each wt% relates to the resin solid body and complement each other to form 100wt%.
