A method of coating an article comprising: forming a suspension of particles of a molten mixture of resins, said mixture comprising between 95 and 30% by weight of a thermoplastic copolyester resin having a vitrification temperature between about 40º C and about 120º C , and between 5 and 70% by weight of another thermoplastic copolyester resin having a vitrification temperature between about -50º C to about 40º C, the difference between the vitrification temperatures, of the two resins being at least 15º C, heating the article to be coated to at least the melting temperature of the mixture, to contact the heated article with the resin particles for a time sufficient for the resin particles to coat, and adhere, to the article, to remove the article from contact with the suspension of resin particles when a resin coating of the desired thickness has been deposited on the article, vitrif Remove the coating and cool the composite article.
