I have seen them called one-thought adjectives, compound adjectives, and compound modifiers. The construction is an adjective combined with a noun or participle used as a noun. These two words then act as a single adjective to modify a noun.
Here is an explanation of the use of a hyphen I copied from the National Geographic style manual. Other style manuals may have different guidlines.
A compound with an ordinal, a comparative, or a superlative is not hyphenated except to prevent ambiguity:
fifth largest city
farthest reaching trade
the best known person
the first ever race
second-growth timber third-ranked convention city best-selling novel faster than normal ship
