PURPOSE: A process for preparing artificial leather by improving peeling property of release paper and urethane resin and processability of resin is provided, which produces abrasion resistant artificial leather capable of optionally forming a pattern without limitation and relation with a release paper pattern. CONSTITUTION: This process comprises the steps of: preparing a polyurethane sol by adding a pigment and a solvent to polyurethane; preparing a PVC sol by mixing a plasticizer, a stabilizer, a filler, ceramic powder, a foaming agent and a pigment to PVC resin; preparing an intermediate product by coating the polyurethane sol on release paper, gelling, coating the PVC sol on the polyurethane resin, foaming in an oven, coating a two-component adhesive on the obtained foaming layer, removing the solvent and adhering to fabrics; and forming a pattern by pressing at 170 to 180deg.C with an embossing machine and gravure printing or surface treating.
