Robert,
It does not stand for Moisture Resistant but Melamine Resin as I understand, It is what the glue is made up with. It can be moisture resistant but you need to check to make sure that it is. Here is something from a plywood mfg website.

MR plywood is made with sustainable managed resources and our customers benefits from stable quality supplied.

We offer both interior and exterior plywood to cater to the needs of the furniture.

MR Grade plywood is very popular in the market owing to its unique bonding strength and durability. We take care to bond it with a Melamine giving it capabilities to exceed its category and perform in some area’s like WBP Plywood.

A specific stress relieving process is employed to keep the product dimensionally stable through a modern tenderising machine.

MR Plywood is very suitable when used for furniture, instruments, and semi – outdoor wooden products.

Melamine –noun Chemistry 1. a white, crystalline, slightly water-soluble solid, C3N3(NH2)3, used chiefly in organic synthesis and in the manufacture of resins, esp. melamine resins.

"slightly water-soluble"

The finished product is primed with kilz and finished with 2 coats of exterior paint.

sounds promising... but I'll have to do more research.
