The present invention relates to radiation curable coating composition (1) consisting essentially of: -from 20 to 95 wt % of one or more (meth)acrylated compounds (a), from 5 to 80 wt % of one or more metal salts of a C10 to C22 fatty acid (b), and -optionally, from 0 to 10 wt % of one or more additives (c), wherein the wt % of compounds (a) to (c) add up to at least 95%, preferably add up to 100%. Compositions of the invention are compatible with a whole range of radiation curable materials and with the standard additives like the standard matting agents. Compositions of the invention permit to obtain a dead matt effect using lower amounts of matting agents like silica and/or waxes. Dead matt effects can be obtained over a wide range of coating thicknesses.

The present disclosure discloses a waterborne inorganic anti-doodling ceramic paint for indoor walls and preparation method thereof; the ceramic paint is a dual-coating paint having an under-coating paint and a surface-coating paint. The advantage effects of the present disclosure is that: the main film-forming materials are inorganic materials, the solvent is mostly deionized water, VOC emission is extremely low, thereby having a characteristics of safety, health and environmental protection; overcoming the shortcomings of multi-components of ceramic paint needs to be aged before use, while the under-coating paint and the surface-coating paint of the present disclosure are all single-component and can be directly used, easily to apply and fast; having an anti-doodling effect, when a marker doodling on the walls, it can be easily erased; the coating has a low surface tension which can isolate the outdoor moisture and prevent the walls from getting wet and mildewed.

The wet adhesion of a coating composition may be improved through the use of voided latex particles as opacifying agents which contain a hollow interior as well as an outer shell of a polymer containing functional groups such as amino, 1,3-diketo, urea or ureido. Other types of functional groups may be introduced to the outer shell polymer in order to vary other desired characteristics of the coating. The voided latex particles are non-film-forming.
