Abstract
A laminate can comprise a substrate, an adhesion promoter layer, and a coating layer, wherein the adhesion promoter layer may include a silane compound of formula (1): Xm—Si—Yn (1), wherein X is at least one of OR, NR2, or SR, or a combination thereof, with R being substituted or unsubstituted alkyl or aryl; Y is CH═CH2 or L-CH═CH2, with L being phenyl or C1-C5 alkyl; m is 1-3, n is 1-3, with m+n=4. The adhesion promoter layer can provide strong adhesion of the coating layer to the substrate by forming covalent bonds with the substrate and covalent bonds with the coating layer.
Claims20
A laminate comprising:
- a substrate;
- an adhesion promoter layer directly overlying the substrate, the adhesion promoter layer including a silane compound of formula (1):
- Xm—Si—Yn, (1),
- wherein X is at least one of OR, NR2, or SR, or a combination thereof, with R being alkyl or aryl;
- Y is CH═CH2 or L-CH═CH2, with L being phenyl or C1-C5 alkyl;
- m is 1-3, n is 1-3, with m+n=4;
- and
- a coating layer directly overlying the adhesion primer layer.
A method of forming a laminate, comprising:
- applying an adhesion promoter layer directly on an outer surface of a substrate,
- wherein the adhesion promoter layer comprises a silane compound of formula (1):
- Xm—Si—Yn(1), wherein X is at least one of OR, NR2, or SR, with R being alkyl or aryl;
- Y is —CH═CH2 or L-CH═CH2, with L being phenyl or C1-C5 alkyl;
- m is 1-3, n is 1-3, with m+n=4;
- and
- applying a coating layer directly overlying the adhesion promoter layer.
A method of manufacturing an article, comprising:
- applying a layer of a curable composition on a substrate, wherein the substrate comprises an adhesion promoter layer including a silane compound of formula (1):
- Xm—Si—Yn, (1), wherein X is at least one of OR, NR2, or SR, or a combination thereof, with R being alkyl or aryl;
- Y is CH═CH2 or L-CH═CH2, with L being phenyl or C1-C5 alkyl;
- m is 1-3, n is 1-3, with m+n=4, and wherein the curable composition comprises a polymerizable material including at least 80 wt % of at least one multi-functional vinylbenzene monomer based on the total weight of the polymerizable material;
- bringing the curable composition into contact with a superstrate;
- irradiating the curable composition with light to form a cured layer;
- removing the superstrate from the cured layer to obtain a laminate;
- and
- manufacturing the article from the laminate.
