The present invention relates to a method for preparing a multiplicity of containers of paints or pre-paints from separate vessels containing an aqueous solution of a rheology modifier, optionally an aqueous dispersion of an opacifying pigment, an aqueous dispersion of polymer particles, and an aqueous dispersion of organic polymeric microspheres. The process of the present invention provides a simple and cost-effective way of preparing a wide variety of a large quantity of contained and finished paints at point-of-sale.

Fluorinated photoinitiators and polymerizable compositions including such fluorinated photoinitiators and at least one free-radically polymerizable monomer, oligomer, or mixture thereof. Multilayer films including a substrate and at least a first layer overlaying a surface of the substrate also are described, in which the at least first layer includes a (co)polymer obtained by polymerizing the foregoing polymerizable compositions. Processes for making a multilayer film using the polymerizable composition also are taught. Articles including the multilayer film also are disclosed, in which the article preferably is selected from a photovoltaic device, a display evice, a solid-state lighting device, a sensor, a medical or biological diagnostic device, an electrochromic device, light control device, or a combination thereof.

The present invention provides antifouling coating compositions having excellent long-term storage stability and provides an antifouling coating composition that can maintain the stable dissolution and antifouling performance of a coating film without causing coating film defects such as cracks in seawater for a long term, such that an antifouling coating film having increased environmental safety can be formed. The present invention provides an antifouling coating composition containing: (A) a triorganosilyl ester-containing copolymer obtained from a mixture of (a) a triorganosilyl (meth)acrylate monomer represented by general formula (1):

##STR00001##

(here, R.sup.1 is a hydrogen atom or a methyl group; and R.sup.2, R.sup.3, and R.sup.4 are the same or different from each other and each represents a C.sub.3-6 alkyl group branched at the α-position or a phenyl group) and (b) an ethylenically unsaturated monomer copolymerizable with the triorganosilyl (meth)acrylate monomer; and (B) calcium sulfate hydrate.
