Abstract
Abstract A latex-based coating composition having high gloss and improved block resistance comprising a plasticized vinyl resin latex containing fillers and dispersed therein microfine polyolefine particles. Though these compositions can be coated upon a wide variety of substrates, they are particularly valuable in the preparation of coated acoustical ceiling tiles to produce good gloss and reduce blocking. The invention also includes said acoustical ceiling tiles coated with said coating composition.
