<p>A printable carpet material which carpet material comprises a fibrous face, a primary backing sheet and a backing layer comprising a bitumen backing composition containing a thermosetting amount of a hydroxyl-terminated polybutadiene-diisocyanate urethane polymer to provide a heat stable carpet material subject to a wet steam printing process without substantial carpet material edge loss or distortion. A method of preparing a carpet material which is steam printable and which method comprises applying as a backing layer to a fibrous carpet material a bitumen backing composition containing a thermosetting amount of a hydroxyl-terminated polybutadiene-diisocyanate urethane polymer which permits the carpet material so prepared to be subject to wet, steam printing processes without substantial carpet material edge loss or distortion.</p> |
