主权项 1. An aqueous color composition for paper and/or paperboard having a solids content of 60-74 wt. % and consisting of: a pigment selected from the group consisting of calcium carbonate, kaolin, calcinated kaolin, talc, titanium dioxide, gypsum, chalk, satine white, barium sulphate, sodium aluminium silicate, aluminium hydroxide and any mixture thereof, optionally starch and/or known additives used in coating compositions selected from the group consisting of preservatives, dispersing agents, defoaming agents, lubricants, hardeners, optical brighteners, and a combination thereof,- optionally a latex binder selected from the group consisting of styrene butadiene (SB), styrene acrylate (SA), polyvinyl acetate (PVAc) latex, and any combination thereof, a binder substitute, wherein the binder substitute is a styrene acrylate copolymer comprising a starch having a mean particle size less than 80 nm and obtained by copolymerization of ethylenically unsaturated monomer in the presence of a starch having an amylopectin content >80 wt. % and an intrinsic viscosity from 0.05 to 0.12 dl/g, and water.
