摘要:
The present invention relates to pigmented coating slip suitable for the production of coated papers and boards containing(a) a coating pigment,(b) 5 to 20%, based on the coating pigment, of at least one synthetic binder,(c) optionally, 0.01 to 20%, based on the coating pigment, of a naturally occurring binder,(d) optionally, 0.01 to 5%, based on the coating pigment, of a cobinder,(e) 0.01 to 5%, based on the coating pigment, of an optical brightener,(f) 0.01 to 5%, based on the coating pigment, of at least one water-dispersible polyisocyanate, and(g) optional additives.
摘要:
This invention relates to compositions comprising a polyisocyanate having ionic groups or polyether groups and at least one member selected from the group consisting of a naturally occurring polymer, a polysiloxane graft copolymer, a water-dilutable synthetic polymer and a cationic polymer or a naturally occurring polymer and at least one member selected from the group consisting of a polysiloxane graft copolymer, a water-dilutable synthetic polymer and a cationic polymer.
