Abstract: Described is a process for producing adhesive-coated articles, wherein an aqueous dispersion adhesive composition comprising a dispersed adhesive polymer and a dissolved polyvinylpyrrolidone is applied at high web speed to a film substrate using a coating machine having at least one rotating roller and wherein the coated film substrate may optionally be bonded to a further substrate. Also described is the use of polyvinylpyrrolidone as a defoamer for aqueous dispersion adhesive compositions applied to a film substrate using a coating machine having a rapidly rotating roller.
