摘要：
An aqueous sol of colloidal particles of tungstic oxide (WO.sub.3)-stannic oxide (SnO.sub.2) composite having a particle size of from 2 to 7 millimicrons is prepared by blending an aqueous solution of tungstic acid and an aqueous solution of an stannate in a weight ratio of from 0.5 to 100 as WO.sub.3 /SnO.sub.2. Where the WO.sub.3 -SnO.sub.2 composite sol in an amount of from 2 to 100 parts by weight as the total of WO.sub.3 and SnO.sub.2 is blended with a sol of a 3- to 5 valent metal oxide having a particle size of from 4 to 50 millimicrons in an amount of 100 parts by weight as the metal oxide, a modified metal oxide sol of colloidal particles having a size of 4.5 to 60 millimicrons as surface-coated with the tungstic oxide (WO.sub.3)-stannic oxide (SnO.sub.5) composite colloidal particles is prepared.
