Preparation of recording materials for inkjet printers

A process for the preparation of a recording material comprising applying an aqueous coating composition to one or both sides of a sheet of paper for an inkjet printer wherein said coating composition is an aqueous dispersion consisting essentially from 20 g/l to 200 g/l of starch and from 0.5 to 50 g/l of a copolymer formed by emulsion copolymerization of 100 parts by weight of a monomer mixture consisting essentially of

• (a) from 10 to 65 parts by weight of a monomer selected from the group consisting of styrene, .alpha.-methylstyrene, acrylonitrile, methacrylonitrile, and mixture thereof,
• (b) from 30 to 85 parts by weight of a monomer selected from the group consisting of acrylic ester with a C.sub.1 -C.sub.18 alcohol, methacrylic ester with a C.sub.1 -C.sub.18 alcohol and mixtures thereof,
• (c) from 0 to 25 parts by weight of a monomer containing tertiary amino group, a monomer containing a quaternary amino group, or a mixture thereof, and
• (d) from 0 to 20 parts by weight of another monoethylenically unsaturated monomer in an aqueous medium in the presence of from 12 to 300% by weight, based on total monomer mixture, of a synthetic cationic protective colloid .
