A Monte Carlo photon-tracing method is applied to calculation of the reflectance from alkyd paint films. Challenges inherent in the study of paint films, such as the high density of particle packing and pigment particle flocculation are considered. A naIve modification to the propagation behaviour of photons in Monte Carlo simulation geometries is proposed to account for the close packing of scattering particles and is shown to be effective when used with a reasonable correction for pigment particle flocculation. Initial investigations consider paint films consisting of a white pigment, rutile titanium dioxide, suspended in a near-transparent binder material. The effects of changing the microscopic properties of pigment particles, such as particle size and shape, on the reflectance from paint films are calculated. The changes in reflectance caused by varying macroscopic paint film properties, such as film thickness, are explored. Simulation work is extended to calculate reflectance from films containing, in addition to rutile titanium dioxide pigment, tint particles and hollow polymer beads (microvoids). The most important conclusion drawn from this thesis is that Monte Carlo methods can be used to calculate the reflectance from paint films.
