grayscale.css

img.grayscale {
    filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0\'/></filter></svg>#grayscale"); /* Firefox 10+, Firefox on Android */
    filter: gray; /* IE6-9 */
    -webkit-filter: grayscale(100%); /* Chrome 19+, Safari 6+, Safari 6+ iOS */
}

What Klaymen says would work, but it is not a good practice.
You shouldn't force IE10 to render like IE9. I suggest that you check out this tutorial that solves grayscale images even on IE10 and IE11.

I suggest that you use this solution that is cross-browser friendly way making images grayscale even on Internet Explorer. Here is the demo - http://www.majas-lapu-izstrade.lv/cross-browser-grayscale-ie11
