An imitation leather laminate material comprises a base sheet consisting of 50 to 90% by weight of a microfiber felt wherein said microfibers are polyethylene terephthalate or polyamide 6 or polyamide 6--6 of from 0.05 to 0.4 denier, and 50 to 10% by weight of a polyurethane-polyurea polymer having an average molecular weight corresponding to a polymer solution viscosity within the range from 10,000 to 50,000 centipoise (cps) when the solution is 25% by weight in dimethylformamide at a temperature of 20.degree. C.; the resulting base sheet has final weight within 140 to 450 g/m.sup.2 and density within 0.20 to 0.40 g/cm.sup.3 and is backed with one or more functional substrates adhered thereto.
