1. A method of making an electrochromic (EC) laminate device comprising a first interlayer sandwiched between a first substrate having first and second surfaces, and a second substrate having first and second surfaces, wherein the first surfaces of the first and second substrates are coated; and further comprising a second interlayer sandwiched between the second substrate and a third substrate, wherein the method comprises:
(a) depositing a pattern of a molten electrolytic thermoplastic composition on the first surface of the first substrate to form the first interlayer, wherein the pattern comprises at least one of lines and beads;
(b) contacting the first surface of the second substrate with the pattern;
(c) placing a film of a thermoplastic polymer to form the second interlayer on the second surface of the second substrate followed by placing of the third substrate on the film to form a subassembly;
(d) applying vacuum to the subassembly and heating the subassembly and applying pressure thereto; and
(e) forcing the thermoplastic composition and the second interlayer to flow to form a laminated device.
