Abstract
A compounded and plasticized vinyl chloride polymer layer, optionally supported such as with a fabric, contains an outer adherent and stain resistant layer having durability and flexibility comprising the crosslinked reaction product of a reactive polyester having free carboxylic acid groups and an alkylated benzoguanamine-, urea- or melamine-formaldehyde resin. The vinyl chloride layer may be printed or embossed or both printed and embossed, optionally printed again, before the outer layer is applied.
Claims24
A laminate comprising
- A. a first layer selected from the group consisting of a fabric backed compounded and plasticized vinyl chloride polymer layer and a compounded and plasticized vinyl chloride polymer layer free of a fabric backing and
- B. an outer second layer on and adherent to said first layer exhibiting stain resistance, durability and flexibility and comprising the crosslinked reaction product of at least one reactive polyester resin having free carboxylic acid groups and at least one amino resin selected from the group consisting of an alkylated benzoguanamine-formaldehyde resin, an alkylated urea-formaldehyde resin and an alkylated melamine-formaldehyde resin.
The method which comprises applying to the outer surface of a first layer selected from the group consisting of a fabric backed compounded and plasticized vinyl chloride polymer layer and a compounded and plasticized vinyl chloride polymer layer free of a fabric backing, a second layer of a catalyzed mixture of at least one reactive polyester resin having free carboxylic acid groups and at least one amino resin selected from the group consisting of an alkylated benzoguanamine-formaldehyde resin, an alkylated urea-formaldehyde resin and an alkylated melamine-formaldehyde resin, and heating said mixture to at least about 200.degree. F. for a period of time sufficient to cure and crosslink said second layer to provide good adhesion of said second layer to said first layer and to provide said second layer with good stain resistance, durability and flexibility.
A wall covering comprising
- A. a first layer selected from the group consisting of a fabric backed compounded and plasticized vinyl chloride polymer layer and a compounded and plasticized vinyl chloride polymer layer free of a fabric backing and
- B. an outer second layer on and adherent to said first layer exhibiting stain resistance, durability and flexibility and comprising the crosslinked reaction product of at least one reactive polyester resin having free carboxylic acid groups and at least one amino resin selected from the group consisting of an alkylated benzoguanamine-formaldehyde resin, an alkylated urea-formaldehyde resin and an alkylated melamine-formaldehyde resin.
