Latin Modern Math font has slanted integrals:

http://www.gust.org.pl/projects/e-foundry/lm-math

XITS Math have default slanted integrals as well as optional upright

ones:

https://github.com/khaledhosny/xits-math

Both fonts use the new OpenType MATH table and thus need an application

that support it for proper math typesetting, namely MS Office 2007+,

XeTeX and LuaTeX.

STIX fonts also provide both:

XITS Math supports the mathematical variants using variation sequences

that are listed here:

Many TeX math fonts have slanted integrals.
