NOVELTY - Coating composition comprises (a) 60-70 %mass siloxane modified acrylic polyol polymer, (b) 5-40 %mass at least one curing agent, (c) 15-25 %mass at least one fluid medium, (d) 0.1-3 %mass at least one additive, (e) optionally, 0.5-1.5 %mass at least one acid catalyst, (f) optionally, 0.1-5 %mass at least one nanoparticle, and (g) optionally 0.1-5 %mass at least one polyolefinic component. USE - The coating composition is used for preparing a siloxane modified acrylic polyol polymer. ADVANTAGE - The coating composition saves time of total process of manufacturing, improves productivity, has self cleaning, easy to clean and anti-graffiti properties, is fluorine free and highly durable, can be dry wiped without the use of hazardous solvents, is capable of being cleaned only by the use of dry wiping of any permanent marker stains, crayon stains, white board marker stains, or sketch pen stains, has desired slip property, has desired mar resistance property, and is simple, cost-effective and environmentally friendly. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a process for preparing the siloxane modified acrylic polyol polymer comprising (i) mixing at least one first monomer, at least one second monomer, at least one siloxane monomer, and at least one first initiator in at least one first fluid medium in a reactor at a first temperature for a first time period in the presence of an inert gas to obtain a mixture, (ii) digesting the mixture at a second predetermined temperature for a second time period to obtain a digested mixture, (iii) adding a second initiator to the digested mixture followed by reacting at a third predetermined temperature for a third predetermined time period to obtain a reaction mixture, (iv) cooling the reaction mixture to a fourth predetermined temperature followed by mixing a second fluid medium for a fourth predetermined time period to obtain a cooled mixture having a solid content of 40-80 %mass, and (v) filtering the cooled mixture to obtain the siloxane modified acrylic polyol polymer; and (2) a process for preparing the coating composition comprising mixing predetermined amounts of at least one curing agent, at least one fluid medium, at least one additive, optionally at least one acid catalyst, and optionally nanoparticles to a siloxane modified acrylic polyol polymer, at a fifth predetermined temperature for a fifth predetermined time period to obtain the coating composition.
