1. A hot melt adhesive composition comprising:
(A) a polyolefin-polydiorganosiloxane block copolymer, where the polyolefin-polydiorganosiloxane block copolymer comprises unit formula (I):
where each RL is an independently selected divalent hydrocarbyl group, each R1 is an independently selected a monovalent hydrocarbyl group, each R3 is independently selected from a hydrogen atom and a monovalent hydrocarbyl group free of terminal aliphatic unsaturation, each R5 is an independently selected hydrogen terminated polyolefin, each R6 is an independently selected divalent polyolefin, each subscript a is independently 1 or 2, each subscript b is independently 0 or a positive number; subscript w is 0 to 2, subscript x is 0 or a positive number, subscript y is 0 or a positive number, subscript z is 0 to 2, a quantity (w+y)≥1, a quantity (x+z)≥1, with the provisos that when subscript w=0, subscript z is >0 and when subscript z=0, subscript w>0;
(B) a polydiorganosiloxane; and
(C) a polyorganosilicate resin.
