The laminated films composed of　photoresponsive liquid crystalline (LC) polymer layer on a photoinert LC polymer film surface were prepared by Langmuir-Schaefer method. Then, the laminated films were irradiated with UV light through a photomask at LC temperature. We newly found that a surface relief pattern with a larger height difference than the photoresponsive layer were formed. This result indicates that the photoinduced mass transfer were propagated from the topmost surface photoresponsive layer. In this presentation, we discuss the photoinduced mass transfer in terms of surface tension gradient and viscosity change of polymer materials.
