Strippable paint and surface regulating and release agents for same paint

A surface regulating agent to be used in combination with a strippable paint including a nonaqueous dispersion type resinous liquid including a solvent containing aromatic hydrocarbon in an amount ranging from 30 to 45% by weight relative to said solvent, and acrylic copolymer resin particle dispersed in said solvent in an amount ranging from 20 to 30% by weight relative to said nonaqueous dispersion type resinous liquid, said acrylic copolymer resin particle being formed of acrylic copolymer having a chain structure including at least one of acrylic acid monomer and methacrylic acid monomer having ethylenic unsaturated bond and carboxyl group, said acrylic copolymer resin particle having an acid value of not lower than 90 and a glass transition temperature ranging from 25 to 40° C.;

• diethylene glycol monoether contained in said nonaqueous dispersion type resinous liquid in an amount ranging from 7 to 13% by weight of a resinous solid content of said nonaqueous dispersion type resinous liquid;
• and polyether-chemically modified polysiloxane compound contained in said nonaqueous dispersion type resinous liquid in an amount ranging from 0.5 to 2% by weight of the resin solid content of said nonaqueous dispersion type resinous liquid;
• said surface regulating agent comprising diacetone alcohol in an amount of not less than 90% by weight.

A release agent to be used in combination with a nonaqueous dispersion type resinous liquid including a solvent containing aromatic hydrocarbon in an amount ranging from 30 to 45% by weight relative to said solvent, and acrylic copolymer resin particle dispersed in said solvent in an amount ranging from 20 to 30% by weight relative to said nonaqueous dispersion type resinous liquid, said acrylic copolymer resin particle being formed of acrylic copolymer having a chain structure including at least one of acrylic acid monomer and methacrylic acid monomer having ethylenic unsaturated bond and carboxyl group, said acrylic copolymer resin particle having an acid value of not lower than 90 and a glass transition temperature ranging from 25 to 40° C.;

• diethylene glycol monoether contained in said nonaqueous dispersion type resinous liquid in an amount ranging from 7 to 13% by weight of a resinous solid content of said nonaqueous dispersion type resinous liquid;
• and polyether-chemically modified polysiloxane compound contained in said nonaqueous dispersion type resinous liquid in an amount ranging from 0.5 to 2% by weight of the resin solid content of said nonaqueous dispersion type resinous liquid;
• said release agent comprising water, sodium metasilicate in an amount ranging from 2 to 5% by weight, and hydroxyethyl cellulose in an amount of 1 to 3% by weight.
