Abstract:
A method of transparentizing a cellulosic substrate which comprises;a) providing a cellulosic substrate;b) applying to a surface of the substrate a composition which includes at least one compound selected from compounds of the formula: ##STR9## wherein R"" is any mono- or polyfunctional organic radical;R is H or CH.sub.3 ;R' is H or --C(O)C(R).dbd.CH.sub.2, with the proviso that --C(O)C(R).dbd.CH.sub.2 occurs at least once;x is an integer 0-4 and indicates the number of functional groups on R"" which are reactive with ethylene or propylene oxide;z is an integer 1-4 and may vary independently of x and n;n is an integer 1-20 and is independent of x and z; andwherein if any of R, R', or R"" are greater than one, their identities and the number of each may be the same or different; or ##STR10## wherein R"" is any mono- or polyfunctional organic radical;R is H or CH.sub.3 ;R' is H or --C(O)C(R).dbd.CH.sub.2, with the proviso that --C(O)C(R).dbd.CH.sub.2 occurs at least once;x is an integer 0-4 and indicates the number of functional groups on R"" which are reactive with ethylene or propylene oxide;z is an integer 1-4 and may vary independently of x and n;n is an integer 1-20 and is independent of x and z; andR'"" is H or a group of the formula: ##STR11## wherein R, R', and n are as defined as above, wherein if any of R, R', R"" or R'"" are greater than one, their identities and the number of each may be the same or different; andc) curing the composition with radiation.
