Abstract:
A surface treated substrate comprising at least two treated surface layers and a substrate, wherein a first layer constituting an outermost treated surface layer is a layer comprising composition (I), and wherein a second layer, constituting an underlayer in contact with said first layer, is a layer comprising composition (II):wherein the composition (I) comprises: a composition containing an organic silicon compound of the formula (1): â€ƒwherein each of R1 to R3 is methyl or a group of the formula (2), provided that at least one of R1 to R3 which are contained in one molecule is the group of the formula (2); R1, R2 and R3 are the same or different; m is an integer of from 1 to 100; and n is an integer of from 0 to 10; â€ƒwherein A is a C2-10 bivalent hydrocarbon group or an oxygen atom; R4 is a C1-10 monovalent hydrocarbon group; Q is isocyanate, chlorine or alkoxy having the formula OR5; provided that R5 is a C1-6 monovalent hydrocarbon group, a P number of R4 is the same or different from the others; a (3-P) number of Q is the same or different from the others; and p is an integer of from 0 to 2; wherein the composition (II) comprises: a composition comprising a fluorine-containing reactive silane compound which forms a surface having a contact angle of at least 100Â° to water, wherein said surface treated substrate has an initial rolling angle of from 4Â° to at most 10Â°.
