Abstract

Simulation of paint's reflectivity by applying the Monte- Carlo technique has been performed. The necessary for simulation probability characteristics have been estimated from known paint's optical parameters, such extinction, single scattering albedo, scattering indicatrix of the elementar volume, reflection indicatrix of a substrate and optical thickness of the layer. The contrast coefficient and hiding power of a paint have been found from calculation of a diffuse reflectivity of the layers at black - R_B and white - R_W substrates. The computation has been performed for a paint with the following optical constants: pigment - n_p equals 2.53, (chi) _p equals 2 (DOT) 10^-2, and binder - n_b equals 1.56, (chi) _b equals 4 (DOT) 10^-5. The developed technique may be applied to prediction of hiding power in various paints.
