Provided is a transparent and light-weight ballistic resistant safety glazing comprising an ionomer sheet. The ionomer sheet comprises an ionomer derived from a parent acid copolymer that comprises copolymerized units of an &#x3b1;-olefin having 2 to 10 carbon atoms and, based on the total weight of the acid copolymer, about 20 to about 30 wt % of copolymerized units of an &#x3b1;,&#x3b2;-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms. The ionomer is neutralized to a level of about 5% to about 90%, based on the total carboxylic acid content of the acid copolymer, and further comprises at least one cation. Further provided are articles comprising the light-weight ballistic resistant safety glazing.
