Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
38 words
An article having at least one essentially flat major surface which has been treated with a composition containing a compound having at least one aziridine functionality so as to render said surface more adherent to subsequently applied layers.
Claim 2
Dependent Claim
38 words
An article having at least one essentially flat major surface which has been treated with a composition containing a compound having at least one aziridine functionality so as to render said surface more adherent to subsequently applied layers.
Claim 3
Dependent Claim
38 words
An article according to claim 1 having a rigid layer adhered to said treated surface, wherein said composition further contains at least 0.1 part by weight of an organic resin per part by weight of said aziridine-functional material.
Claim 4
Dependent Claim
17 words
An article according to claim 1 wherein said intermediate layer is insoluble in trifluoroacetic acid at 20°C.
Claim 5
Dependent Claim
53 words
An article according to claim 1 wherein said aziridine-containing material has the formula wherein A 1 is an n valent organic or inorganic group; R 1 , R 2 , R 3 and R are independently selected from hydrogen and lower alkyl groups; and n is a whole number of at least 1.
Claim 6
Dependent Claim
23 words
An article according to claim 1 wherein said treatment comprises the product resulting from the interaction between said article and said aziridine-containing material.
Claim 7
Dependent Claim
29 words
An article according to claim 5 wherein said product is the result of chemical reaction between functional groups present at the surface of said article and said aziridine-containing material.
Claim 8
Dependent Claim
24 words
An article according to claim 5 wherein said product is the result of mechanical interlocking between fissures in said surface and said aziridine-containing material.
Claim 9
Dependent Claim
21 words
An article according to claim 5 wherein said product is the result of entrainment of said aziridine-containing material in said surface.
Claim 10
Dependent Claim
18 words
An article according to claim 1 wherein said article further comprises a functional layer on said modified surface.
Claim 11
Dependent Claim
15 words
An article according to claim 9 wherein said functional material comprises a magnetic recording medium.
Claim 12
Dependent Claim
13 words
An article according to claim 9 wherein said functional material comprises an adhesive.
Claim 13
Dependent Claim
13 words
An article according to claim 9 wherein said functional material comprises a silane.

An article according to claim 9 wherein said functional material comprises a radiation sensitive composition.
Claim 16
Dependent Claim
14 words
An article according to claim 9 wherein said functional material comprises an abrasive material.
Claim 17
Dependent Claim
17 words
An article according to claim 9 wherein said functional layer comprises a film of a polymeric material.
Claim 18
Dependent Claim
73 words
An article comprising a rigid support having opposed parallel major surfaces, a first layer on one of said major surfaces comprising an aziridine-functional material and an organic resin wherein said organic resin is present in an amount of at least 0.1 part by weight per part by weight of said aziridine-functional material, a second layer on said first layer comprising an actinic radiation curable adhesive, and a polymeric film on said second layer.
Claim 19
Dependent Claim
73 words
An article comprising a rigid support having opposed parallel major surfaces, a first layer on one of said major surfaces comprising an aziridine-functional material and an organic resin wherein said organic resin is present in an amount of at least 0.1 part by weight per part by weight of said aziridine-functional material, a second layer on said first layer comprising an actinic radiation curable adhesive, and a polymeric film on said second layer.
