摘要

A method is described for the synthesis and compositions of matt/satin aqueous dispersions of colours, with low side lustre and improved ability of the titanium dioxide granules to radiate light. The improved coverage of the titanium dioxide at a particular value of side lustre, is achieved, on one hand, by using roasted porous diatomite and on the other, by a suitable combination of pigment mixture, suitable granulometric composition and structure in a ratio by volume between them of 18/82 to 60/40. The PVC of the colours is between 40% and 60%.;οών αο¶Yώ@;Y@j®ΎΟΎ @νώY@¶­@Ήκ­®οΉ@ϋYώ@Ήµ­®jΉοώ @½ ¶½­@µΟY¶ώϋx @ΟώYΉΚΎ @Y¶aΉY¶ώ­jk@Yύx @Κύοµώϋx @νµYύ ΟY @ο@λού¶ώ½j­@ώϋY­ϊ¶¶Y@ΉϋοΟ Ήο½ @¶Ύµ@ὶϊ @YΚϊ@¶Ύµ @ϋϊϋϋΎµ @¶Ύµ@ΟώΎΌοώΟ;Ύµ@¶Ύµ@¶ώ¶Y­;ΎµK@f@λού¶;½Ή@¶ @ϋYύµΚ¶ώϋx @ώϋY­ϊ¶¶Y @¶Ύµ@ΟώΎΌοώΟ;Ύµ@¶Ύµ@¶ώ¶Y­;Ύµ@νώY@Ήµνϋοϋώj­@¶ώx@Κύοµώϋx @νµYύ ΟY @οΚώ¶µν ­ο¶Yώ@ΟώY@¶ @ΉώΎΚΎώxΉο½ @Κοαµνj­Ύµ@ΚΎΟΎµ @ΟώY¶Ύ;¶@Yαο­ϊ @ϋYώ@Yαο¶jΎµ@ϋY¶ ύύύΎµ@Ήµ­ΟµYΉΎκ@;νY¶Ύ @Κνj­¶½­k@ϋY¶ ύύύΎµ@ϋΎϋϋΎο¶ώϋx @ΉµΉ¶ Ήο½ @ϋYώ@ΟΎx @ϋYώ@οώ @Y­YύΎν;Y@ϋY¶}ϊνϋΎ@ο¶YΌκ@¶½­@YΚϊΰ
