The invention deals with a transparent substrate clad with a stack of layers comprising one or more essentially mineral layer(s) exhibiting a nonzero volume fraction of at most 74 % of pores of 30 to 100 nm, and a minimum thickness of at least the dimension of the largest pores that it contains and, as appropriate, one or more essentially mineral dense layer(s) of thickness(es) at most equal to 400 nm, on condition that two dense layers such as these are not neighbours, and that at least one porous layer is covered by at least one other layer; and with - a method of preparing this substrate, by liquid route implementing a structuring latex.
