Finely divided particles can be provided in a simple manner and with good adhesion with a coating which is a polyfunctional organosilane and/or a hydrolysis product thereof, and/or a reaction product thereof with an organosilane which contains a hetero atom and/or with an alkoxide.

Coated particles containing a monomeric, polyfunctional organosilane coating

Dye-donor element for use according to thermal dye transfer methods comprising a support having on one side a dye layer and on the other side a heat-resistant layer comprising a binder and inorganic particles having a volume average particle size of at least 1 .mu.m, said heat-resistant layer optionally carrying a topcoat comprising a lubricant, wherein said inorganic particles substantially consist of a mixture of a first type of inorganic particles, which are silicate particles having a Mohs hardness below 2.7, and of a second type of inorganic particles, which are silicate or carbonate particles having a Mohs hardness of at least 2.7 in a ratio by weight of said first type to said second type of inorganic particles comprised between 20:1 and 1:2.
