    Abstract: Binder preparation with a minimum film-forming temperature below 10 degrees C, based on a dispersion containing anionic and non-ionic emulsifiers and a copolymer of 20-50 wt% vinyl-aromatic monomer, 45-70 wt% 1-18C alkyl acrylate or 5-18C alkyl methacrylate which forms a homopolymer with a Tg below 10 degrees C, 2-4 wt% methacrylic acid and optionally other comonomers. A binder preparation with a minimum film-forming temperature (MFT) below 10 degrees C, based on a binder polymer (P) in the form of an aqueous dispersion containing anionic emulsifier(s) and non-ionic emulsifier(s), in which (P) is a copolymer of (A1) 20-50 wt% vinyl-aromatic monomer(s), (A2) 0-15 wt% 1-4C alkyl (meth)acrylate(s), (A3) 0-30 wt% (meth)acrylonitrile, (B) 45-70 wt% monomer(s) which form a homopolymer with a glass transition point (Tg) below 10 degrees C, selected from 1-18C alkyl acrylates and 5-18C alkyl methacrylates, (C) 2-4 wt% methacrylic acid, (D) 0-3 wt% monomer(s) selected from amides, 1-4C hydroxyalkyl esters and 1-4C alkyl-polyalkyleneoxide-esters of 3-6C mono-unsaturated monocarboxylic acids and (E) 0-5 wt% other monomer(s), where the total amount of monomers (A1)-(A3) does not exceed 55 wt% of the total monomer content and the content of (A2) is at least 5 wt% if the content of (A3) is less than 0.5 wt%. An Independent claim is also included for emulsion paint containing binder preparation(s) as described.

    Abstract: Pigmented, water-based, solvent-free coating material containing an aqueous binder comprising a dispersion of copolymer based on alkyl (meth)acrylate monomers plus 3-6C mono-unsaturated monocarboxylic acid in amounts of less than 1 wt%, with a total polar comonomer content (including these acids) of 0.1-10 wt%. Pigmented, water-based coating material, essentially free from volatile, water-insoluble organic compounds, containing (I) an aqueous binder with a minimum film-forming temperature (MFT) of not more than 5 deg C, based on an aqueous dispersion of polymer(s) (P) derived from (A) 90-99.9 wt.% of at least two different types of monomer comprising (A1) 2-12C alkyl acrylates and (A2) 1-12C alkyl methacrylates, (B) from 0 to less than 1 wt.% 3-6C mono-unsaturated monocarboxylic acid, (C) 0-0.5 wt.% 4-6C mono-unsaturated dicarboxylic acid and/or unsaturated sulfonic acid, (D) 0-2 wt.% amides of mono-acids of type (B), (E) 0-5 wt.% 2-4C hydroxyalkyl esters of (B) (E1) and/or esters of (B) with poly-(2-3C alkylene oxides) (E2), (F) 0-5 wt% mono-unsaturated monomers with urea groups and/or mono-unsaturated monomers with an acetylacetoxy group (CH3COCH2COO-), where the total amount of (B) and (C) is less than 1 wt% (based on A-F) and the total amount of (B-F) is 0.1-10 wt.%, (II) inorganic pigment particles, (III) optionally inorganic filler particles and (IV) typical auxiliary substances for coating materials. The coating material contains less than 0.05 wt% Photoinitiators (based on P) and has a pigment volume concentration (PVC) of more than 20.
