Abstract

Det er beskrevet en fremgangsmåte for påføring av et belegg, fortrinnsvis et grunnbelegg, på narvsiden av et lær, spesielt et kveglær, idet en vandig plastdispersjon (4) omfattende kompakte partikler inneholdende et esemiddel påføres på denne narvsiden og tillates å størkne, og hvor hule mikrosfærer (7) dannes fra de kompakte partiklene ved tilførsel av varme. I henhold til oppfinnelsen er det forutsett at den størknede plastdispersjonen (4) inneholdende de kompakte partiklene vil eksponeres mot infrarød stråling som har en bølgelengde mellom 0,7 µm og 100 µm.There is disclosed a method of applying a coating, preferably a base coating, to the scar side of a leather, particularly a cattle leather, wherein an aqueous plastic dispersion (4) comprising compact particles containing a blowing agent is applied to this scar side and allowed to solidify and where hollow. microspheres (7) are formed from the compact particles by the application of heat. According to the invention, it is envisaged that the solidified plastic dispersion (4) containing the compact particles will be exposed to infrared radiation having a wavelength between 0.7 µm and 100 µm.
