For purposes of illustration, these some sizing systems are detailed further below.

Nonaqueous dispersion sizing system

Term " nonaqueous dispersion resin ", " NAD " and similar statement refer to shell-core structure comprising utilize high molecular weight Component (" shell component "), by highly polar high molecular weight resin particulate constituent (" core component ") stable dispersion in low polar solvent Non-aqueous liquid media in and obtain resin.

Nonaqueous dispersion resin can be prepared via a method which, in the method, according to conventional methods, by polymerizable alkene Belong to unsaturated monomer in the presence of shell component (dispersion stabilizer), dispersin polymerization is carried out in hydrocarbon solvent, wherein polymerizable Ethylenically unsaturated monomer dissolves in the polymer (core component) of hydrocarbon solvent and polymerizable formation insoluble in the hydrocarbon solvent, the shell Component is by the polymer that is dissolved in or swells in the solvent.

Non-aqueous dispersion figure resin used in the present invention can be resin known per se, or can be according to known tree The resin of rouge production.This non-aqueous dispersion figure resin and preparation method thereof is described in ,=for example, US 3,607,821, US 4, 147,688, US4,493,914 and US 4,960,828, Japanese patent application publication No. 29,551/1973 and Japanese Laid-Open Patent Publication In number 177,068/1982.Specifically, it can be used the various polymer substances for being dissolved in low polar solvent as composition non-aqueous dispersion The shell component of figure resin, wherein the polymer substance is described in such as 4,960,828 (Japanese Laid-Open Patent Publication number of US 43374/1989) in.

In view of the soil resistance of final lacquer coat, the shell component of such as acrylic resin or vinyl can be used.

The copolymer with highly polar ethylenically unsaturated monomer usually can be used as core component.Preferably, non-moisture The core component of granular media type resin has free acidic-group or can be by hydrolysis in the seawater at the first silicon of acidic-group Alkyl group, or combinations thereof.It is preferred that 5-75wt%, for example, the monomer of the nuclear polymer of 5-60wt% or 7-50wt% should band There are free acidic-group or silicyl ester group, or combinations thereof.Match since free acidic-group will directly affect coating Preparation, and silicyl ester group has an impact after only hydrolyzing in the seawater, therefore currently preferably has overweight free acid Property group.
