Abstract

"SISTEMAS AQUOSOS CONTENDO PRé-MISTURAS DE ADITIVOS E PROCESSOS PARA PREPARAR OS MESMOS". A presente invenção se refere a um aditivo para sistemas aquosos pigmentados compreendendo uma mistura de um polímero catiónico e uma partícula inorgânica aniónica de elevada área superficial, métodos para preparar e usar o aditivo, métodos para preparar um revestimento aquoso colorido para papel bem como uma matriz de celulose revestida com a mesma; e um processo para preparar pré-misturas estabilizadas."WATER SYSTEMS CONTAINING PREMIXES OF ADDITIVES AND PROCESSES TO PREPARE THE SAME". The present invention relates to an additive for pigmented aqueous systems comprising a mixture of a cationic polymer and a high surface area anionic inorganic particle, methods for preparing and using the additive, methods for preparing a colored aqueous paper coating as well as a matrix. of cellulose coated therewith; and a process for preparing stabilized premixes.
